Kristen DelMastrowrote a review of La Sportiva Katana Rock Climbing Shoe - Women's Discontinued Rubber on September 29, 2009
These shoes are great. It took me a few days to get used to them...as it does any new pair of footwear, but once I did, they feel great. I definitely think my confidence in tiny footholds has increased with these shoes.
I wear an 8.5 in street shoes and when I tried these on at a local shop the guy only had a 38 and they're perfect....I don't do the whole way too small shoe thing either. A 38.5 would probably feel great too, but a 39 or 40 (which is what the size chart suggests) would be floppy.
